SPECIFICATION forming part of Letters Patent No. 407,283, dated July 16, 1889. Application filed May 26, 1889. Serial No. 312,169. (No model.)

T all whom it may 007110677 4 denotes rotary clasping-studs, which are Be it known that I, ALBERT II. DEAN, a preferably made slightly larger than usual, citizen of theUnited States, residingatBridgeeach stud having a head 5, and a shank cut port, in the county of Fairfield and State of away upon one side under the head, as at 6, 5 Connecticut, have invented certain new and so as to give to the said shank a greater and s 5 useful Improvements in Corset-Clasps; and a lesser diameter. In practice each stud is I do hereby declare the following to bea full, ordinarily provided with a base 7,which rests clear, and exact description of the invenupon the surface of the busk. This, howtion, such as will enable others skilled in the ever, is not essential, as a shoulder would to art to which it appertains to make and use serve as well. The shanks of the studs pass 60 the same. through the busk, and the lower ends there- My invention relates to the class of corsetof are rigidly secured, ordinarily by'hea'ding 'clasps in which the busks may be engaged down, to plates 8, which are provided with and disengaged in the usual manner, or all slots 9. It should be understood that the of the studs may be disengaged by a single shanks of the studs turn freely in the busks, 65 movement without moving the busks toward but are rigidly secured to the plates, so that each other. the studs can only be turned by the oscilla- My invention consists, first, in providing tion of the plates. At the back of busk 3 is a one of the busks with eyes made in the usual slide 10, provided with studs 11, which pass manner and provided at their outer ends through slots 9 in plates 8, and also through 70 with slots leading into the openings which slots 12 in said busk, and are provided with receive the studs, and in the use in connecheads 13 upon the upper side thereof, theretion therewith of rotating studs upon the by holding the slide firmly in position upon other busk, so constructed that in one posithe busk, but permitting it to move freely tion they will pass readily through said. slots thereon.

and in. another position will be retained by l l is a spring connected to the lower end the eyes; and my invention consists, secondof the slide and also to the busk, the operaly, in operating mechanism by which I am tion of which is to hold the slide at its norenabled to rotate all of the studs simultamal position and studs 4 at the clasping poneously to enable the busks to be unclasped sition, as in Figs. 2 and l. This spring, how- 80 by a single movement. ever, is not essential to the operativeness of In the accompanying drawings, forming the device, it being apparent that if the 7 part of this specification, Figure 1 is an elespring were omitted a single downward movevation of a portion of the front of a corset, ment of the slide only would be required to 3 5 showing my improved clasp's in use, the eyes turn the studs to the clasping position. WVhen 85 and studs being in the clasping position; Fig. the spring is used, it causes said studs to as- 2, an elevation of the busks and the parts opsume the clasping position the moment the crating therewith detached from the corset, slide is released after having been moved to the parts being in the clasping posit-ion, as turn the studs to the unclasping position. 40 in Fig. 1, looking up; Fig. 3, an elevation of The slide may be operated in any suitable' 'gc the busks and parts operating in connection manner. I have shown a stud 15 upon the therewith in the unclasping position; Fig. 4, slide as passing through a slot 16 at the upa cross-section on the line 00 so in. Fig. 2; and per end of busk 3 and as provided with a ring Fig. 5 is a similar section on the line 3 y in 17 for convenience in operation.

Fig. 3. 18 denotes the eyes, which are rigidly se- 5 Similar numbers denote the same parts in cured to bush 2 by rivets 19. These eyes are all the figures. provided with the usual openings 20, of suit- 1 denotes the sections of a corset, which able size to receive the heads of the claspingmay be of ordinary or any preferred construcstuds, and with slots 21, of suitable size to retion; 2, the eye-busk, and 3 the stud-husk. ceive the shanks of the clasping-studs, but loo not the heads thereof. In addition to the usual opening and slot, I provide a slot 22, extending through the outer edge of the eye into slot 21. Slots 22 are 01": just sufficient size to allow the lesser diameter of the clasping-studs to pass through when turned to the unclasping position, as in Figs. 3 and 5. \Vhen in the clasping position, the greater diameters of the clasping-studs rest against the outer ends of slots 21, thereby holding the busks clasped together in the usual manner. It will be seen, therefore, that when the busks are in the clasped position there are two ways of unclasping them, the first being the ordinary way, which is to move the busks toward each other until the shanks of the claspingstuds pass out of slots 21, which leaves the heads of said studs free to pass through openings 20. The other mode of unclasping is to rotate the studs, as I have already de scribed.

Figs. 2 and 4: show the parts at what I call the clasping position that is, the greater diameters of the clasping-studs are in en gagement with the outer ends of slots 21. In order to disengage the bush, it is necessary to move slide 10 upward against'the power of spring 14. When this movement is made, studs 1.1 on said slide are caused to travel up slots 9 in plates 8, the normal position of slots 9 and 12 being oblique to each other, as clearly shown in Fig. 2. It follows, therefore, that as stud 11 are moved upward the clasping-studs will be rotated, the construction and organization being such as to move cut-away portion 6 of the clasping-studs from the position shown in Figs. 2 and 4, where the busks are held firmly clasped together, to the position shown in Figs. 3 and 5, in which the lesser diameters of the clasping-studs are brought to register with slots 22 at the outer ends of the eyes. In this position of the claspiiw-studs the busks readily unclasp outward-that is, away from each other-41o movement toward each other being required, as in unclasping ordinary studs and eyes.

Having thus described my invention, I claim- 1. A corset-clasp comprising a bush having eyes, each of which is provided with a slot at its outer edge leading to the central opening, and a second busk having rotary elaspingstuds, said studs being cut away upon one side, so that when in position they will remain in engagement with the eyes, and when partially rotated they will pass through said slots, so that the busks may be disengaged without movement toward each other.

2. A corset-clasp comprising a pair of busks, one of which is provided with rotary studs cut away upon one side, the otherbeing provided with eyes having openings to receive the heads of the studs, slots extending therefrom toward the outer edge thereof, which receive the shanks of the studs, and reduced slots leading to the outer edge, of suitable size to allow the studs to pass through when the lesser diameter is presented thereto, but to hold the busks in the clasped position when the greater diameter of the studs is presented thereto.

3. A corset-clasp comprising a pair of busks, one of which is provided with rotary studs cut away upon one side, the other busk being provided with eyes having openings 20, of suitable size to receive the heads of the studs, slots 21, of suitable size to receive the greater diameter of the studs, and slots 22, leading to the outer edge, of suitable size to allow the studs to pass through when the lesser diameters are presented.

4-. A corset-clasp comprisinga pair of busks, one of which is provided with rotary studs 4, cut away upon one side, and slots 12, plates attached to the inner ends of said studs and provided with slots 9, said slots lying obliquely to slots 12, and a slide having studs 11 passing through slots 9 and 12, so that when said slide is moved either upward or downward the greater or lesser diameters of studs 4: are placed in operative position, the other busk being provided with eyes adapted to be engaged by the greater diameter of stud 4 in the usual manner, and having slots 22 at the outer edges thereof, which allow stud 4 to pass out when the smaller diameters are placed in 0perative position, but which hold said stud in the clasped position when the greater diameter is in operative position.

In testimony whereof I atiix my signature in presence of two witnesses.
